On the Non-observability of Recent Biogenesis
Charles H. Lineweaver, Tamara M. Davis
Abstract
In a previous paper we addressed the question "Does the Rapid Appearance of Life on Earth Suggest that Life is Common in the Universe?" The non-observability of recent biogenesis is a self-selection effect that needs to be considered if inferences are to be drawn from the rapidity of terrestrial biogenesis. We discuss several approaches that have been proposed to take this effect into account.
